compiling cpia_pp without dma brings up the following warning :

gcc -c  -Wall -Wstrict-prototypes -O2 -pipe -fomit-frame-pointer 
-fno-strength-reduce -I. -I/usr/src/linux/include -D__KERNEL__ -DMODULE 
-D_DEBUG_ -DCONFIG_VIDEO_CPIA_MODULE -DCONFIG_VIDEO_CPIA_PP_MODULE 
-DCONFIG_VIDEO_CPIA_USB_MODULE cpia_pp.c
cpia_pp.c: In function `cpia_parport_enable_irq':
cpia_pp.c:259: warning: implicit declaration of function `mdelay'

and both insmod'ing cpia_pp and depmod -a bring up :

/lib/modules/2.2.14/misc/cpia_pp.o: unresolved symbol mdelay
